Centerless grinding machines play a critical role in refining metal components used in crushing and sand-making production lines. These machines ensure precision grinding of shafts, rollers, and other wear parts without requiring centering, improving efficiency and reducing downtime.
Modern centerless grinders for aggregate applications offer:
– High Rigidity: Designed to handle hard metals like chromium alloy.
– Automated Feed Systems: Enable continuous processing for bulk production.
– Precision Tolerance: Achieves ±0.005mm for critical components.
| Model | Max. Grinding Diameter (mm) | Power (kW) | Grinding Wheel Speed (rpm) |
|---|---|---|---|
| CG-200 | 200 | 15 | 1,450 |
| CG-350 | 350 | 22 | 1,200 |
In sand and gravel plants, centerless grinders maintain crusher rotor shafts and conveyor rollers, ensuring smooth operation. For example, a granite processing line in Texas reduced maintenance costs by 30% after adopting CG-350 machines for roller refurbishment.
Q: How often should grinding wheels be replaced?
A: Typically every 500–800 hours, depending on material hardness.
Q: Can these machines process stainless steel?
A: Yes, with appropriate coolant and wheel grit selection.
A Canadian plant integrated two CG-200 units to regrind hammer crusher pins annually, extending part life by 40% and cutting replacement costs by $15,000/year.
